I used to do that too. But Vista seems a bit more stable in that way. This PC has had Vista on it for about 8 months and is still going strong. If there is one way I think Vista is definitely superior to XP it is in regards to not gradually getting slower and more corrupt as time goes on. It's only early days of course but this PC just doesn't seem to be falling apart like PC's always seem to do with XP.
I think we all seem to agree on the majority of things. Our differences are relatively minor I think.
Like splash said. Don't pay for two OS's Vista has it's problems but for the average user there really aren't any showstoppers. Yes you get slow hdd transfer's with large files but the majority of that is being sorted in SP1. I've not seen the problem after installing RC1 but if people say it's still happening then it must still be happening. But as it only happens with large file transfers it's hardly something most people are going to be having to deal with every day.
